DATV: Replace DVB-S2 pilot VLA buffers with std::vector

Browse Source 
Replace variable-length arrays used for DVB-S2 pilot symbol matching with
std::vector allocations.

Use vector::data() when passing buffers to the existing pointer-based
match_ph_amp() function. This removes non-standard VLA usage and improves
C++ portability without changing behavior.
